Rotork flow control products have

been selected for applications

throughout the giant Queensland

coal seam gas-to-LNG (Liquefied

Natural Gas) projects in Australia.

To date, Rotorks international

sales network has received orders

for more than 5000 valve actuators,

embracing electric, electro-

hydraulic, pneumatic and gas-over-

oil technologies.

The three projects Queensland Curtis LNG,

Santos GLNG and Australia Pacific LNG - aredeveloping coal seam gas in Queenslands Surat

and Bowen Basins. Hundreds of kilometres of

pipelines will link the natural gas production

wells on the Queensland mainland with a world-

class LNG production plant under construction

on Curtis Island, which will initially produce more

than twenty seven million tonnes of LNG for

export each year. These coal seam gas projects

are centred on a clean and efficient energy

source with half the carbon dioxide emissions

of coal.

For the upstream mainland wellheads, HART

(Highway Addressable Remote Transducer)enabled Rotork CVA modulating electric

actuators have been ordered for process valve

control at an eventual total of 2000 widely

distributed sites. In addition to the natural

flow on the extraction process for coal seam

water. This resource will be treated for use by

agricultural and industrial customers as well as

supplementing domestic water supplies.

CVA actuators deliver continuous, repeatable

modulating control with a programmable fail

to position option. Resolution, repeatability

and hysteresis performance is less than 0.1%

of full scale, offering suitability for the most

demanding control valve applications. Among

other advantages, innovative CVA electric

actuation removes the expense of installing and

maintaining instrument air supplies at these

remote sites, where the pressure of the gas

itself is too low to provide a viable source for

actuator operation.

CVAs are also preferred because electric

actuation eliminates the release of any

environmentally harmful gas into the

atmosphere during valve operations as well

as facilitating solar powered operations in the

remote locations.

Nearly 1000 Rotork Skilmatic SI and EH

range electro-hydraulic actuators have been

ordered for control valves, shutdown valves,wellhead skids and metering skids. These self-

contained actuators combine the simplicity and

convenience of electrical operation with the

modulating precision of hydraulic actuation and

the reliability of mechanical failsafe motion.

Designed to SIL3 standards for use in safety

critical applications, Skilmatic actuators are

also programmable for partial stroke testing,

enabling valves to be tested without interrupting

routine processes.

The orders for Rotork electric actuators are

completed with IQ actuators for various

isolating valve automation duties. All the Rotorkelectric actuator ranges feature advanced and

user-friendly non-intrusive programming and

commissioning technologies, combined with

integral data logging, diagnostics and asset

management capabilities.

The balance of Rotork orders on this giant

project involves fluid power actuators for the

pipeline and the LNG plants on Curtis Island.

The majority of these are CP and GP range

pneumatic actuators operating butterfly valves

on LNG production lines.

valve on the water extraction line. The Skilmatic Model SI-Q60 on the right is controlling a 4 inch (DN100)

safety shutdown ball valve on the gas line.

electric actuator designs share versions of

this technology.

The actuators are customised with control

packages to meet specific operating duties,

including SIL2 and SIL3 applications.

The remainder are GO range gas-over-oil

actuators, most of which are for the large

mainline pipeline shutdown valves.

GO actuators are designed to use the pressure

of the pipeline gas as the motive power source.

Integral control functions facilitate a wide range

of duties, usually safety related and including

line break, low pressure close, high differential

inhibit and ESD.

Rotork GO actuators (above) are built on a modular

basis and incorporate integral control functions for

a wide range of duties which are usually safety related.

Rotorks international sales network has made an

important contribution to this success, with orders

received at Rotork offices in Australia, China, Singapore,

Italy and the USA. As well as providing a simplified

contractual route for the different products, the Rotork

global organisation has the ability to co-ordinate

manufacture at various production centres and secureon-time deliveries to customers across the world. In

Australia, Rotork has moved to larger premises in order

to fully support the Queensland projects.

For over 30 years Schischek

has been supplying electricexplosionproof products for

building services and HVAC

applications in many industries,

including onshore and offshore oil

and gas, refineries, chemical plants,

laboratories, pharmaceuticals,

water treatment and ship building.

Schischek actuators enable Rotork

to increase activity in hazardous

and non-hazardous area HVAC

markets and also fill a gap in the

product range which is applicable

to small valves, especially in the

processing industries.

Schischek manufactures electric actuators

for quarter-turn and linear valve and damper

operation, each available with a spring-return

failsafe capability and with Ex or Red

explosionproof or In non-explosionproof

enclosure specifications.

The Max range is manufactured in two body

sizes for quarter-turn operation at output

torques between 5 and 150 Nm with anon-site selectable stroke time of 3, 15, 30,

60 or 120 seconds. The selectable stroke

time is one of a number of options that are

built into the standard product, including the

adaptable power supply and choice of on/

off, three-position or modulating control. For

position signalling and feedback a 4-20 mA or

0-10V supply can be utilised, whilst two end of

travel auxiliary position switches are optionally

available. The ExMax and ExRun actuators have

a T6/T5 Temperature and IIC Explosion Group

classification enabling them to be used safely in

ATEX rated Zones 1 and 21 in the presence of

dangerous gases, mists and vapours. The T6/T5

Focus on Schischek actuators

temperature classification enables the actuator

to operate at ambient temperatures up to

40C/50C and an integral heater automatically

maintains reliable actuator operation at

temperatures down to -40 C, facilitating the

installation of standard products in extremeenvironments.

For failsafe operation in either direction an

integral spring return version is available for

output torques up to 60 Nm, which can be

programmed to operate with a 1, 3, 10 or

20 second stroke time. In its failsafe version

the actuator is available with SIL2 safety

integrity level approval. Max actuator duties in

explosionproof environments include dampers

for smoke, temperature or fire protection

and the operation of ball and butterfly valves,

typically in sizes up to 50 mm (2 inches).

For linear on/off, three-way or regulating

control, Run actuators offer an output torque

range of 500 to 10,000 N and stroke lengths

between 5 and 60 mm. Up to five running

times between 2 and 15 seconds per millimetre

are selectable on-site, together with the self-

adaptable power supply and choice of position

signal and feedback supply. The Run actuator

is not available in a linear failsafe configuration,

but this function is achieved by the combination

of a Max actuator and Lin gearbox. The Lin

converts the actuators quarter-turn output into

a linear stroke, selectable at lengths between 10

and 42 mm.Both Schischek and Rotork are known for

manufacturing products of the highest quality

and reliability. These products complement

each other and enable Schischek to significantly

extend its offering in the HVAC market,

supported by Rotorks worldwide presence in

almost 100 countries.

Rotorks rack and pinion pneumatic actuators

are one example of a product that gives

Schischek the ability to increase its offering to

encompass electrical sensors and monitoring

equipment with electric and pneumatic

actuation. In another scenario, Rotorks range

of larger explosionproof electric actuators can

be used with Schischek actuators to increase

versatility and scope of supply. Motorway

tunnels in Melbourne, Heathrow Airports T5

terminal and the London Olympic Village are

just three of many locations where Rotork IQ

intelligent electric actuators are used for fire

control and HVAC applications. Power stations

are another area of activity, where large linear

and rotary Rotork electric and pneumaticactuators are used for applications including the

modulating control of inlet and draft dampers

for boiler combustion control.

At the other end of the size range, Rotorks

abilities in the process industries benefit from

the option of using Schischek electric actuators

to control small linear valves requiring up to

10 kN operating force and quarter-turn valves

with torque requirements up to 150 Nm. By

providing isolating and modulating control with

a failsafe function, these products sit neatly

below Rotorks ranges of electric control valve

actuation products, including CVA and CMAprocess control actuators, broadening the scope

of supply in plants containing large and small

bore pipework and introducing the option of an

all-electric solution in every area of the process.

Retrofit upgrade replaces actuators after sixtyyears unbroken aerospace industry service

Dating from 1953, the Rotork

Model 100A actuators were part of

a contract to operate the valves on

one of the worlds first large scale

supersonic wind tunnels. Designed

and built by the then newly formed

Aircraft Research Association

at Bedford, the Transonic Wind

Tunnel was an ambitious project

created to keep the British aviationindustry at the cutting edge of

technology by testing the effects of

supersonic speeds on new aircraft

designs. The facility is operated

by a 25,000 hp AC motor and a

13,000 hp DC motor. In addition

a 10,000 hp compressor is used

to provide extra power to enable

testing at high transonic and

supersonic speeds up to mach 1.4

(1065 mph approx).

In the early 1950s Rotork was still

in its infancy and the award of thissignificant and prestigious contract

was a milestone on the route to

the establishment of what is now

the worlds leading manufacturer

of valve actuators and flow control

products. Since the wind tunnel

was first commissioned in 1956

it has been in virtually continuous

daily operation, testing military

and civil aircraft from around the

world. It has played a vital role

in the development of legendry

projects including the TSR2, Harrier

jump-jet and Concorde. Today the

work continues with programmes

including Airbus, the Eurofighter

Typhoon and the Lockheed Martin

F-35 JSF.

Remarkably, although designed for

isolating valves, the Rotork 100A

actuators have been performing

modulating duties throughout their

sixty years of service, constantly

altering the position of large gate

valves by small degrees to control

the level of wind speeds and

provide the data that is needed for

the highly accurate measurement

of test results. It is the automation

of this process with a bespoke

control system incorporating a

Modbus control network whichhas necessitated the replacement

of these units with new IQ3M

actuators that are specifically

designed for modulating duties.

Because there is a constant

demand to use the wind tunnel,

careful and detailed planning

has taken place to ensure that

the retrofit operations can be

successfully completed in the brief

periods of time that are availablebetween test programmes. The

restricted access around the valves

also demands particular attention.

Detailed planning paid off when

the first two actuators were

removed and the replacement

IQ3M actuators installed and

commissioned in two days, half

the allocated time allowed before

the wind tunnel was due to

re-start operations.

Richard Harvey, Senior Process

Engineer at the Aircraft ResearchAssociation, is pleased with

Rotorks contribution to the

success of the project. He explains:

We are currently undergoing a

1.5million upgrade programme

for equipment that controls our

Transonic Wind Tunnel. One

of the packages of work that is

being undertaken is to replace

our auxiliary compressor valve

drive units. These were selected

because they are amongst the

oldest pieces of equipment on site

and they are being used on a daily

basis. The existing Rotork 100Aactuators have functioned very

well considering they are being

used well outside of their rated

specification, but at 60 years old

they were due for retirement.

The replacement valve drives

needed to be very reliable and have

an accurate positional indication as

they are vital for the operation of

the tunnel and the data we collect.

We approached Rotork with our

specification who pointed us in

the direction of the new IQ3M35actuator. I was delighted with the

vast amount of information and

precise control that I could achieve

using the Modbus interface card.

The installation was a success and

the tunnel drivers have reported

that the new actuators provide

them with much better control.

We are now looking towards our

next maintenance period where

the remaining actuators are due to

be replaced.

Some of the very first valve actuators to carry the

Rotork name are being replaced with the companys

latest intelligent IQ3 actuators after sixty years ofunbroken service on a demanding and critical duty in

the aerospace industry.

Compressor stations along the

route are designed to preserve

the pressure level in the networks

and transfer the gas for local

area consumption. These are

among the pipeline locations

where Rotork valve actuation

technologies are widely utilised.

The compressor station on the

natural gas pipeline at Erzincanin eastern Turkey, serving the

countrys Anatolian area, is a

typical example. Here, Rotorks

well established agent Omas

Teknik Pazarlama Temsilcilik

has supplied, installed and

commissioned actuators for

operational and safety-related

duties.

The Erzincan station consists of

four turbine/compressor units

maintaining a pipeline flow rate

of between 1.6 and 2 millionstandard cubic metres per hour,

which helps to increase the

networks overall transportation

capacity. Rotork valve actuators

are integrated into an ABB

automation system that controls

the compressor station and other

processes including a high integrity

safety system for emergency

shutdown, instrumentation and

other electrical equipment.

The safety-related valve duties are

performed by Rotork GO Rangegas-over-oil actuators operating

ISO Class 600 ball and plug valves

in 16 inch and 48 inch sizes. The

GO Range uses the pipeline gas

as the motive power source. The

gas is delivered to oil tanks that

convert the gas into hydraulic

pressure and this pressurised

hydraulic oil is used to drive Rotork

scotch-yoke quarter-turn or linear

valve actuators.

Using pressurised oil as the

driving force provides powerfuland smooth actuator control

and isolates the cylinder from

the pipeline gas. This prevents

contaminants from entering the

hydraulic cylinder, eliminating

corrosion and seal deterioration

and extending actuator life.

At the centre of the gas-over-

oil system, the multi-function

manifold block integrates gas

control functions to facilitate

a wide range of valve control

options. Standard gas controlsystems are complemented with

optional equipment for functions

including Line Break, Low Pressure

Close, High Differential Inhibit

and Emergency Shutdown (ESD).

The manifold has the facility for

a high-flow hand pump, pressure

relief and a locking handle for safe

commissioning. High pressure and

low pressure control logic designs

are also available, together with

torque limiting devices for valve

and drive train protection.

Rotork GO actuators are

IP66M/67M third party certified

and approved for environmental

protection, together with CE and

ATEX hazardous area certification.

The standard working operating

pressure range is 10 to 105 barg,

enabling a quarter-turn operating

torque of up to 600,000 Nm and

linear thrust of 5,000,000 N to suit

pipeline valves of virtually all sizes

and description.

Operational isolating duties atErzincan are performed by Rotork

IQ intelligent valve actuators with

secondary gearboxes, operating

ISO Class 600 ball valves in 24, 28

and 48 inch sizes. The benefits of

IP68 watertight and ATEX certified

Rotork IQ actuator technologies

are widely recognised for isolating

and regulating valve duties in the

oil, gas and pipeline industries. The

use of solid-state electronics as an

alternative to switch mechanisms

and counter limiting devices,

combined with programmable

micro-processor based control

and instrumentation functionality,

offers many proven benefits.

Rotork selected for routine and safety-relatedvalvecontrol duties on Turkeys pipeline network

These include non-intrusive

configuration and data transfer by

means of a hand held instrument

via a secure, bi-directional link.

This system is used to perform all

switch setting and commissioning

functions that were traditionally

only achieved by removing

electrical covers. Using the multi-lingual menu on the actuator

display screen, it is quick and easy

to commission the valve, with or

without mains power connected.

The same instrument is used to

download operating information

from the actuators data logger.

The inclusion of a data logger

enables an event-by-event history

of valve activity to be generated,

including torque profiles

produced during each opening

and closing. Using Rotorks IQ-Insight2 software, these can be

compared with the valve torque

signature profile logged during the

commissioning process to identify

the trend of valve operating wear

or isolate tight spots and other

problems. Analysis of this data

improves asset management

through fault diagnostics and

preventative maintenance.

The compressor station atErzincan is one of several in Turkey

that have incorporated Rotork

actuators into the automation

system. Others include Kirsehir,

Eskisehir, Hanak and Sivas, with

more planned for the future.

Rotorks abilities as a single

source for electric and fluid

power actuators, combined with

the expertise, experience and

comprehensive facilities available

at a local level from Omas, provide

vital contributions to the award of

these contracts and subsequentproduct support.

Pipelines carrying products including natural gas

from Asian countries traverse Turkey en-route

for export to other final destinations or as a

source of energy for domestic consumption.

In 2011, an operating division of

Martin Midstream Partners (MMLP)

began building a single product tank

farm at the Port of Corpus Christi,

Texas, consisting of six 100,000

barrel tanks and four booster pumps

to serve nearby truck and ship

loading terminals. Originally, the

facility was designed for a single

hydrocarbon product. The terminals

original specifications did not require

any automated valves to isolate the

individual storage tanks.

During construction, MMLP

decided to upgrade and introduce

the capability to handle a second

product, which necessitated the

requirement of isolating the tanks

to avoid cross-contamination.

To achieve this, MMLP specified

Rotork electric valve actuation

under centralised control. The

explosion proof Rotork IQ non-

intrusive intelligent actuators are

monitored and controlled by a Rotork

Pakscan P3 digital system, designed

specifically for valve actuation duties

and the environments associated

with hazardous area petrochemicalplants and storage areas. The Rotork

system incorporates all appropriate

interlocks which safeguard the

integrity of the terminal operations.

For this project, MMLP has been

able to take advantage of additional

functionality and further economies

through the introduction of Pakscan

P3 with a wireless field network.

Wireless Pakscan eliminates virtually

all the costs associated with the

installation of wiring, cable ducts,

safety barriers and associatedequipment required for network

cabling, whilst enabling an increased

level of information from the

actuators to be communicated over

the wireless network.

Chris Duke, Rotorks lead service

technician on the project, explains:

The customer didnt want to add

a lot of new conduit and wiring to

control the actuators, so the wireless

Pakscan system was a perfect fit.

The installation consists of 16

Rotork IQ40 non-intrusive intelligent

actuators, one Pakscan P3 wireless

master station and three network

repeaters, which are used toovercome radio black spots and

ensure the redundancy of the

network. As far as start-ups go, this

was by far the easiest of any type of

control system that I have seen.

Some pre-commissioning of the

wireless system was performed at

the Rotork factory in Rochester prior

to delivery and, once in the field, I

installed the wireless antennas on

each actuator and gave each unit its

unique address. When this was done

I powered up the master station and,as if by magic, all sixteen actuators

populated the network within a

few minutes. The customer was

very impressed with the job done

and how quickly everything came

together.

Following the success of this project,

the same actuation and control

system will be extended to three

additional tanks to be built during

the second phase of construction at

this facility.

Another golden opportunity

At the same time as the network at the MMLP

plant was being commissioned, the installation

of another wireless Pakscan network was being

completed for an application in an entirely

different industry gold mining.

The Newmont underground gold mine

in Nevada utilises Geotubedewatering

technology to separate sediment from both

ground and extraction process water. The filter

systems, which are installed above ground,

Rotork IQ40 actuators installed on the four booster pumps, again illustrating the simplified site wiring.

are fabricated from a woven material which

is permeable to water while retaining solids

and sludge. Excess water drains through small

pores, resulting in effective dewatering of the

contained material, which is then processed to

extract the gold.

The large scale filtering operation has been

automated by the motorisation of the filter

inlet and isolating valves with Rotork IQ electric

actuators. A total of 15 actuators have been

installed on valves over a widely distributed area

A section of the Geotubedewatering plant, with the Rotork IQ actuators installed on the inlet pipework on

the right hand side. In total there are 12 filter bags, of which 3 can be seen in this view below.

and a Modicon PLC has been introduced to

supervise the operation of the plant.

Here again, the utilisation of the wireless

Pakscan P3 network for the monitoring and

control of the valve actuators has delivered a

reliable and economical solution, eliminating

the cost of installing any additional site wiring

apart from the actuator power cables. All the

actuators are in line-of-sight of the Pakscancoordinator module, with the distance to each

actuator ranging between 68 metres to 132

metres. The externally mounted coordinator

is connected to the Pakscan P3 master station

in the control room by a 15 metre cable. The

master station communicates with the Modicon

PLC using Modbus TCP Ethernet protocol.

James Hall and Mark Dennis from Rotorks service

team complete the non-intrusive commissioning of

one of the 12 Rotork IQT actuators that control the

flow of water into the filter bags.

Rotork Pakscan P3 wireless

First introduced in 2009, the

Rotork Pakscan P3 wireless

network control system is a further

development of the Pakscan

system used in thousands of plants

throughout the world today.

Simply stated, the system

establishes a secure wireless mesh

network that is used to control

actuators and other field devices

throughout the plant and to gather

important operating data for asset

management and preventative

maintenance from the connected

valve actuators.

The wireless system operates on the license-free, globally

recognised 2.4 GHz ISM (Industrial Scientific and Medical)

frequency band and has a line-of-site operating range

between each device of approximately 30 metres indoors

and 100 metres outdoors. Up to 60 actuators can mesh

with a wireless coordinator.

In a Pakscan wireless mesh network, each actuator on the

network can act as an independent router to help signalsget to their intended destination. A correctly designed

network will be configured to provide two or more paths

between each actuator and the wireless coordinator.

Therefore, if the normal traffic route is blocked or if a

hardware or communication failure should occur, it can

be overcome as the network dynamically determines an

alternate route for the data to travel. This self-healing

network mimics the loop-back capabilities of the

established Pakscan two-wire loop.

In such a network, privacy and security are high priorities.

To prevent unauthorised commands being sent to devices

over the wireless network, all control data is encrypted

using the Advanced Encryption Standard (AES). Additionalencryption is incorporated into the system to prevent

unauthorised devices joining the network and to prevent

a message replay attack.

The Pakscan P3 wireless network card gives the user

access to all the standard control and monitoring features

and data available from the wired Pakscan system,

together with the diagnostic and asset management

information stored as standard by Rotork IQ actuator

data logger and configuration files, which is otherwise

only downloadable locally, using the IQ hand held

commissioning and communication tools. Using built-in

web pages it allows easy extraction of these files from the

control room over the wireless network.

The wireless system consists of three

main hardware components:

A Pakscan P3 master station fitted with

a wireless interface module, which is

typically connected to the plants control

Retrofit upgrade at Turkeys largest refinerychooses Rotork valve automation

Retrofit work in progress. Engineers from Omas work on one of the tank farm

manifolds at the Tupras Izmit refinery.

Rotork valve actuation

and two-wire digital

control technology has

been chosen for a major

upgrade and automation

programme at the Tupras

Izmit refinery in Turkey.

Tupras is Turkeys largest industrial

company and leading refiner,

operating four refineries of which

Izmit is the largest. First opened

in 1961, production at Izmit

of commodities including LPG,

naphtha, petrol, jet fuel, keroseneand diesel is now running at over

11 million tons a year.

More than 900 explosionproof

Rotork IQ intelligent electric valve

actuators will be installed in a four

stage project to motorise manually

operated valves on the refinerys

tank farms. Nearly 800 of the

actuators will be retrofitted on

existing valves whilst the balance

will consist of new actuated valve

packages.

Many of the actuators will be

factory fitted with intumescent

fireproof coatings, as shown

picture bottom right.

The non-intrusive, explosionproof

and permanently watertight design

of the Rotork IQ has a proven

record of long term reliability

and low cost of ownership in

the petrochemical industry.

Secure non-intrusive and wireless

technology is utilised for setting

control parameters, commissioning

and downloading integral

dataloggers to provide vital

diagnostic information for asset

management programmes.

The retrofit project at Izmit is

being performed by Rotorks well

established agent in Turkey, Omas

Teknik Pazarlama Temsilcilik.

Omass responsibilities include the

design and fabrication of valve

adaptation, installing the new

actuators, commissioning and on-

site support.

The new actuated valve packages

are being assembled and tested

in the Omas workshops prior to

delivery to site.

The expertise, experience and

comprehensive facilities available

from Omas at a local level are keycomponents in the success of this

major retrofit project.

Due to the size of the refinery

site, groups of IQ actuators in

different areas will be monitored

and controlled by a total of twenty

Rotork Pakscan P3 digital bus

networks. Designed specifically

for valve actuation applications

and the spacious environments

associated with tank farm

installations, Pakscan incorporates

secure field communications withinbuilt network redundancy. Each

network is controlled by a Pakscan

P3 master station which provides

a local centre for monitoring and

control and links the network to

the sites SCADA system.

The tank farm upgrade at Izmit is

part of a massive modernisation

and expansion programme at the

Tupras refinery. This also includes

the construction of new refinery

facilities on an adjacent site by

the Spanish company TcnicasReunidas, for which more than

400 IQ electric actuators are being

supplied through Rotorks Spanish

subsidiary company.

Rotork Australia has supplied

Fairchild Model 10 pressure

regulators for research

applications demanding highly

accurate pressure control at the

TRI Australasia facility near to

Queenslands Gold Coast.

TRI Australasia offers highly specialised

services including a range of geo-synthetic

testing and quality assurance programmes

for a multitude of industries. The Fairchild

Model 10 regulators have been installed on

two processes where compressed air is used

to check for the content of water retention

within clay. Both processes demand highly

accurate set point pressure supplies in order

for the tests to maintain reliable results.

Fairchild Model 10 regulators are designed

for applications where high performance

and reliable set point accuracy are essential.Suitable for system pressures up to 34 bar

(500 psi) and flow capacities up to 63 cubic

metres/hour (40 SCFM), the Model 10 offers

nine set point pressure ranges and is easily

able to achieve the +/- 0.5% accuracy required

for the TRI application.

Commenting on the Fairchild product, TRI

Australasias Divisional Director Warren

Hornsey said We chose the Fairchild

product due to the accuracy required and the

strong name within the industry. It was also

important for us to have the support that

Rotork Australia can offer from their localBrisbane office.

River weir upgrade illustrates Rotorksextended scope capabilities

Another part of Rotorks activity involves

actuators that are retrofitted on site as part of

improvement projects which often also include

additional work such as mechanical, electrical

and civil engineering. The members of Rotorks

dedicated Site Services Division have many years

experience of these projects, enabling themin many cases to organise the total supply of

the work that is required together with project

management services, embracing all of the

project team disciplines in what is called an

extended scope contract.

A major benefit for the customer is the simplified

contractual route that the extended scope

contract enables, by reducing the number of

separate sub-contractor contracts. Extended

scope contracts have become particularly

popular with customers in areas including water,

power and environmental improvement, where

projects can be relatively modest in scale but stilldemand a diverse range of engineering skills and

disciplines. A recent Rotork UK contract for the

Environment Agency at the picturesque village of

Buscot in Wiltshire is a good example.

Above: Buscot Weir after the completion

of Rotorks extended scope contract, which

encompassed project management, new valve

actuation and adaptation, a new control panel in

an adjacent building and the installation of a new

walkway platform for inspection and maintenance.

For many years Buscot Weir on the River Thames

had been equipped with electric motors that

were used to adjust the position of two sluice

gates in order to manage the river level and

flow rate during fluctuating weather conditions.

These motors, with the associated valve shafts

and an electrical control panel in an adjacent

building, had become obsolete and required

replacement to safeguard the river banks from

potential flooding in the future.

As well as replacing all the obsolete equipment,

the Environment Agency wished to ensure that

future inspection and maintenance could becarried out safely. To achieve this it would be

necessary to construct a new access walkway

platform along the length of the weir. Following

the preliminary site survey of the existing

Rotork is well known for

supplying flow control equipment

for new and upgraded industrial

plants and processes on a global

scale. In these contracts, often

involving tens or hundreds ofvalve actuators and associated

control equipment, Rotork works

with valvemakers, engineering

companies and end users as one

of several members of a project

team, each with different areas

of expertise and generally all

under the supervision of a

main contractor.

A companion to the recently

announced HPD diaphragm style

range of regulators, the new HPP

(High Pressure Piston) range

incorporates a piston design to

manage supply pressures up to 413

Bar (6,000 psi) at temperatures up

to 260 C and deliver high output

pressures between 207 Bar (3,000

psi) and 69 Bar (1,000 psi).

The HPP high pressure performance

complements that of the HPD,

which will also manage supply

pressures up to 413 Bar (6,000

psi) and accurately regulate lower

output pressures down to between

35 Bar (500 psi) and 1.66 Bar(25 psi).

Constructed with 316 stainless steel

bodies, the HPP and HPD ranges

feature patent pending improved

valve seat sealing that eliminates

the risk of media leakage often

associated with conventional high

Rotork Australia has supplied

subsea rack and pinion hydraulic

valve actuators and subsea

gearboxes for an innovative

renewable energy wave

technology project on Garden

Island, near Perth in Western

Australia.

Subsea actuators and gearboxes assist first-of-kind commercial wave energy project

The patented CETO (Carnegie Wave Energy)

technology converts ocean swells into a

source of energy for power generation andwater desalination plants. Unlike other wave

technology systems, the CETO wave power

converter is fully submerged and produces

high pressure water from the power of waves.

A submerged buoy moving up and down with

the movement of the waves drives a pump

attached to the seabed.

The pump in turn delivers water ashore

through a pipeline at high pressure that enables

zero-emission electricity or fresh water to

be produced.

Due for completion early in 2014, thePerth Wave Energy Project will be the first

demonstration of a complete grid-connected,

commercial scale CETO power generation

system anywhere in the world.

Rotork actuators and gearboxes have been

ordered by Severn Glocon Australia and include

double-acting hydraulic actuators equipped

with top-mounted diver operated override

gearboxes, controlling subsea ball valves

installed at a depth of 25 metres. The override

gearbox incorporates a lost quadrant system

in the gear pinion, providing a simple but highly

effective mechanism for switching betweenhydraulic and manual operation.

All the diver has to do is rotate the handwheel

to the three positions remote (hydraulic), open

(manual) or close (manual) which are visiblethrough the indicator on top of the gearbox.

Co-operation between Rotork Fluid Systems and

Rotork Gears has enabled a rugged, compact,

well engineered and cost-effective solution to

be delivered for this application.

The patented CETO (Carnegie Wave Energy)

technology.

Rotork equipment includes double-acting hydraulicactuators equipped with top-mounted diver

operated override gearboxes.

Schischek ExMax explosionproof

actuators have been selected to assist the

production of biogas for district heating

systems in the German city of Munich.

Biogas is produced during the effluent treatment

process at the citys largest waste water plant

Klaerwerk Gut Grosslappen, situated close to

the world famous Munich Allianz Arena, home

to Bayern Munich football club.

The Schischek actuators have been installed

in the digester and fermentation tanks, where

all electrical equipment must be approved

for use in hazardous areas. Built inside four

large towers, the fermentation tanks mix the

waste at a defined temperature to produce the

biogas. For optimum performance the inner

tank temperature must be maintained at 38 C.

Six Schischek actuators are installed in an area

known as the lamp at the top of each tower

for the operation of air dampers to balance the

inside temperature with fluctuating ambient

temperatures on the outside. Factors favouring

the Schischek products for this application

Schischek boosts biogas production at Munich waste water plantinclude their compact size, ease of installation,

standardised connections and Zone 1 hazardous

area explosionproof certification. In addition

Schischek, which is now part of the Rotork

Group of flow control companies, has developed

established relationships with the damper

OEM, local engineering companies and the enduser. All Schischek products are manufactured

with colour coding to indicate at a glance the

appropriate hazardous or non-hazardous area of

application. Yellow denotes hazardous zones 1,

2, 21 and 22, red denotes hazardous zones 2 and

22 and green denotes non-hazardous areas only.

Munich waste water treatment works. The Schischek

actuators are installed in the lamp at the top of

each tower.
